With Derbyshire bordered by seven counties, policing its roads for criminals on the move is a daily challenge. In this episode, cops respond to intelligence that a possible cloned vehicle, thought to be responsible for a string of car key burglaries in North-East Derbyshire, is heading towards Chesterfield. Officers pursue and manage to puncture the vehicle's tyres and then chase and arrest two suspects who run into a nearby field. On the M1, officers pull over a driver, where checks reveal he is disqualified and without insurance. He has a previous history of violent offences and they bring him to custody and interview him, having found a flick knife on him and a hammer in his car, all of which he denies have anything to do with any kind of criminality. And near Chesterfield, police hunt for a stolen caravan. Having been alerted by a tracker on the vehicle, the caravan is soon found on an industrial site but the driver makes a run for it.
